The former Denver Broncos offensive coordinator will be formally introduced by the Chargers on Tuesday afternoon.

McCoy met with the Philadelphia Eagles, Chicago Bears and Arizona Cardinals before sitting down with the Chargers on Monday. The Eagles and Bears appeared to have only mild interest, while the Cardinals were a serious suitor.

It's unclear whether the Cardinals' quarterback situation (Kevin Kolb as the incumbent?) vs. the Chargers (Philip Rivers in the prime of his career) had anything to do with McCoy's decision. It certainly didn't hurt.

The Cardinals' best option at this point might be to promote defensive coordinator Ray Horton to head coach. Jay Gruden is the other leading candidate in Arizona. He's interviewing Tuesday with the Jacksonville Jaguars.

This is the second consecutive year the Broncos have lost one of their coordinators to a division rival. Dennis Allen left Denver after one season as defensive coordinator to become Oakland's head coach. The Broncos were 2-0 against Allen's Raiders in 2012.

McCoy's departure is not a surprise. He was a finalist for the Miami head coaching job last year and met with five teams, including the Chargers, about head coaching vacancies this year.

John Fox said Monday, as McCoy headed to San Diego to interview with the Chargers, that the Broncos would be all right if they had to change offensive coordinators.

"No different than when Dennis left a year ago," Fox said. "I think that worked out alright. I don't have any reason to think any different."

Fox hired Jack Del Rio, a former NFL head coach, to replace Allen, and Denver's defense finished the regular season ranked No. 4. Del Rio made some schematic changes to Denver's defense, but the overall philosophy was the same.

The Broncos could look for a new offensive coordinator who would work well with quarterback Peyton Manning and the passing offense he brought from Indianapolis as well as maintain some consistency for the rest of the offensive players who have had to learn multiple systems in the past two years.
